Android循环确定媒体播放器的进度条

Question

@Override
public void run() {
    int currentPosition = 0;
    int total = mediaPlayer.getDuration();
    while (mediaPlayer != null && currentPosition < total) {
        try {
            Thread.sleep(1000);
            currentPosition = mediaPlayer.getCurrentPosition();
        } catch (InterruptedException e) {
            return;
        } catch (Exception e) {
            return;
        }
        pbRingtonePreviewHorizontal.setProgress(currentPosition);
    }
}

上面是更新进度值的代码，这在水平进度条中完美运行..我想要相同的循环进度条。

初始化进度条的代码是

public void onPrepared(MediaPlayer mediaplayer) {
    System.out.println("on prepared");
    if (!mediaPlayer.isPlaying()) {
        isPlayEnabled = true;
        mediaPlayer.start();
        pbRingtonePreview.setVisibility(View.INVISIBLE);
        pbRingtonePreviewHorizontal.setProgress(0);
        pbRingtonePreviewHorizontal.setMax(mediaPlayer
                .getDuration());
        ivRingtonePreview.setImageResource(R.drawable.stop);
        new Thread(this).start();
    }
}
